Like the pose and look, not keen on the post production treatment. You've 'tweaked' the white background and lost any grounding shadow for Emma, so she looks like she is floating. The selection around her is a little harsh too for my liking too.
As this was shot in a studio it is possible to set and position the lights and expose correctly so you don't have to do post production on the floor and background to get them white. Shooting full length in white takes more effort than most studio setups but is possible with a little time and patience.
